Two Black anodised Ceramic bearing 10t jockey (pulley) wheels to fit Shimano eight speed or Campagnolo derailleurs (please check the amount of teeth on your wheels before purchase)
Standard wheels often wear out before the derailleur does reducing shifting quality - replace them and revive your derailleur.
These wheels help to improve drivetrain performance in the following ways:
- Ventilated design drives out mud and debris - a must in the UK or offroad.
- Aluminium construction is more durable than standard plastic wheels.
- Ceramic bearings offer low-drag long life performance.
Each wheel weighs 9g on our scales.
